FAQS
Common Questions
THE ANSWER
TPO, EPDM, and PVC are single-ply membranes used on low-slope commercial roofs. EPDM is flexible and performs well in cold climates. TPO offers heat-welded seams and reflective energy efficiency. PVC provides superior chemical resistance, making it ideal for restaurants and industrial facilities. Selectiondepends on building use, exposure, and performance goals.
THE ANSWER
Commercial roofing system lifespans vary by material and exposure. EPDM and TPO systems typically last 15–25 years, PVC can exceed 25 years, and metal roofing often lasts 30+ years. Lifespan depends on installation quality, maintenance, and environmental conditions such as sun, wind, and thermal cycling.
THE ANSWER
Choosing the right roofing system upfront reduces lifecycle costs by minimizing premature deterioration, cutting emergency repairs, and extending service life. Systems matched to building use, climate exposure, and energy goals also perform more efficiently, reducing operational risks and maintenance frequency over decades.
THE ANSWER
Yes. Greenwood supports manufacturer warranties for the roof systems it installs and can help procure enhanced project-specific warranties when available. Clients may also enroll in the Greenwood Performance Advantage™ (GPA™) program, a proactive maintenance plan that includes regular inspections and documentation to help preserve system performance and maintain warranty compliance.
